ALFRED HARVEY AND HAROLD C. HARVEY, OF MILWAUKEE, WISCONSIN.

MACHINE FOR MANUFACTURING PUMPONS.

Lorenza,

To all feo/0111, t may concern Be it known that we, Airuno Himvnr and HAROLD C. HARVEY, both citizens of the United States, and .residents of lrl'ilwaukee` in the county of Milwaukee and State of lllisconsin7 have invented certain new and useful Improven'ients in Machines for Manufacturing' Pompons; and we do hereby declare that the following is a full. clear7 and exact description thereof.

The primary object of our invention is to provide a machine for forming' pompons or like articles, the same embodying a mandrel about which blanks or strips of material are spirally wound, the last winding' being; cured. t

This invention is particularly applicable to forming` paper culinary oriiaments, the said ornaments having tubular shanks that are adapted to be fitted over the exposed bone portion of a fowlv` chop or other portion of meat, it beingl understood that the ornaments may be used for any purpose other than that specitied.

Specific objects of our invention are to provide means fo1 auton'iatically feeding a strip of materiah preferably papel; from a roll to a forming;l mandrel and by interposine means`r successively frinninn' the strip adjacent to one edge by slitting'. folding; and securing;` the fringed edge1 cutting' sections of the fringed edge strip into blanks and thereafter causing;v said blanks to be wound about the mandrel to form an ornament, having a tubular shank, the last coil of which shank is confined`r and to provide means for stripping` the finished article from the mandrel; to provide means cooperative with the mandrel for `gripping' the forward end of the blank prior to a spiral windingl operation of the latter: to provide means for tei'isioninp; the coils of the blank during' a winding' operation; to provide a shiftable head carrying a series of mandrels that are individually alined with a feeding' point` whereby the blanks arc successively formed into pompons to thus increase the capacity of the machine relative to its speed, and to provide means for holdin g the finished pompons a predetermined interval of time` whereby the securing' means for the last coil will permanently set.

1With the above and other objects in View the invention consists in certain peculiari ties of construction parts as set forth hereinafter with reference Specification of Letters Patent.

Referring by characters to the drawings, 1, 1, represent parallel standards of a frame, which standards are mounted upon a baseplate Mounted between the standards at the feed end of the machine is a roll of paper A, the end of which passes upwardly and over a guide roller 3 and from thence it travels between sets of feed rollers 4, 4', 5, 5', and 6, 6. The upper series 4, 5 and 6 of each set of feed-rollers have spindles which are suitably journaled in bearings with which the standards 1 are provided, the spindles carrying gear-wheels 7, 8 and 9 respectively. The spindle of the intermediate feed-roller 5 also carries a sprocketwheel 10, whereby power is imparted to the series of feed rollers through pinions 11 and 12 that are respectively meshed with the gear-wheels 7 and 8 and 8 and 9.

Mounted in a suitable box with which the frame standard is provided at the discharge end is a crank-shaft 13 that receives its power from any suitable source. T his crankshaft carries a sprocket-wheel 14, which is in belt connection with the sprocket-wheel' 10 of the feed-roller 5, the said sprocketwheel being provided with a second toothed face 10 which is in link-belt connection with a similar sprocket-wheel 15, which sprocketwheel is carried by a shaft 16 that is mounted in suitable bearings that extend from the standard 1 at the feed end of the machine. The shaft 16 carries a rotatory male cutting die 17, which cutting die operates in conjunction with an anvil roller 13, it being understood that the paper strip passes between said die members in its travel forward to the discharge feed rollers 6 and 6. Interposed between the set of slitting or cutting die rollers 17 and 18 and the feedrollers 4 and 4 is a strip-folding formerplate 19, the same being supported by the frame standards and, as shownrin Fig. 12 of the drawings, this edge-folding formerplate at one side thereof is gradually turned up and over to form an open loop whereby the strip when caused to travel therethrough will be similarly folded upon itself.

,Fulcrumed to the frame standards 1 is a yoke 20, which yoke carries a transversely disposed cutting blade 21, that is abutted by an obliquely arranged cutting blade 21', the said blades serving to sever the strip transversely into sections of predeterminedfdimensions. rThe knife yoke 2O has depending spring-controlled arms 22, which arms are connected by a pitman 23 to a cam-actuated lever 22, the same being fulcrumed upon a stud that extends from the adjacent framemember 1. The lever 22 carries an antifriction roller for engagement with a camwheel 24, which cam-wheel is mounted upon the main crank-shaft 13, being provided in this instance with four projecting faces disposed at equal distances apart which successively actuate the cutting mechanism just described.

Mounted upon a bracket that extends from one of the standards 1 is a glue reservoir 25 having a reciprocative discharge nozzle 25 that extends therethrough, its lower end being normally disposed upon a slightly higher plane than that upon which the paper strip travels. rlhis nozzle projects through the reservoirand is engaged by a Vfinger 26, which finger is carried by the knife-yoke`20.` hence with cach downward movement of the knife-yoke the nozzle is caused to move downwardly therewith and its foot portion will thus distribute a small quantity of adhesive material upon the paper co-incident to the latter b-eing severed. This glue-reservoir mechanism forms no part of my invention, it being understood that any means for distributing glue at the `desired point can be employed. Another glue-discharging reservoir 27 is supported by the frame between the intake mouth of the forming plate 19 and rotatory slitting dies 17 and 18, the same being arranged to supply a line of adhesive material to the paper strip there- Linder, which line may be distributed by a constant stream or intermittent drops from the reservoir.

As best shown in Figs. 1 and 3 of the drawings, the rear end of the crank-shaft 13 is journaled in a bearing that is carried by a post 28. The foot portion of this post is secured to the base-plate 2 and its upper portion is merged into a fixed circular shell 29 having a central hub portion 30 in which is mounted an arbor 31. Secured to one end of the arbor is a spidered head 32, and secured to the opposite end of said arbor is a ratchet-wheel 33, movement being imparted thereto by a pair of spring-controlled pawls 34, 34, which are mounted upon arms' 35, 35', the same being loosely journaled upon the spindle. These arms are connected to the oppositely extended crank-portions 36, 36 of the crank-shaft by links 37. As best shown in Figs. 2 and 3 of the drawings each spider arm of the head 32 is looped upon itself at its outer end to form Valined journals 40 for a mandrel 41, the work-receiving end of each mandrel being extended obliquely toward the axis of the head about which axis they are adapted to rotate and invertical alinement with the discharge feed-rollers 6, 6.

Fitted between each pair of journals 40 of the head and secured to the mandrel 41 is a pinion 42 having a shoe extension 43, which shoe extension is adapted-to slide upon a circular track 44 that extends approximately through one-half of the circumference of the shell. rlhe opposite or lower half of the shell 29 is formed with a toothed semi-circular rack 45, which rack is adapted to engage and actuate the mandrel pimons, whereby they will make a predetermined number of revolutions during a semi-rotation of the,y had and therea'tter when the saut pmions travel past the last tooth of the rack as shown in Fig. i', they will be locked against notation due to the sliding engagement be-l tween the pinion shoe .land track ser tion 4st.

In the operation of the device each mandrel is arranged to be brought into aline ment with the point of disel'iarge between the ifeed-rollers t3 and o", there being a momentary delay in the rotation of the mandrei at this point due to the intermittent 'feed n'iovement in'iparted to the head 32 through the crank-shaft and its connections with the pawl and ratchet mechanism carried by the head spindle 3ft. Each mandrel llt carries a spring-controlled gripping tinger 46, as best shown in Fig. 5, the said finger being formed with a stem lft which projects through a transverse aperture adjacent to the base of the work-receiving end of the mandrel. The stem of the gripping finger is connected to a spring lever 4t?, which, in turn, is secured to the body of the spindle. Normally the gripping finger is held seated in a flattened portion ofi' the mandrel by the tension of spring 47 and the said finger is moved outwardly to form clearance between its mandrel seat by an arm 4S of a rocking lever. The rocking lever rigidly secured to a spindle 49 which is ji'nirnaled in the spider arm. A second arm LIl S of said rocking lever is extended outwardly to the opposite side oit the spindle :from that ot its arm 48, the said arm 4:8 serving as a sup port for a presser-foot 50, which presseroot extends longitudinally ofl the working end of the mandrel and is provided with a seat into which the gripping :finger rests when the latter is :forced outwardly or opened. The presser-foot is also provided with flared tongues 5l, which, in conjunction with the spindle form a bell-mouthed throat for guiding the forward end of a blank out 'from the strip of paper A to the periphery of the mandrel. Hence when the mandrel assumes its momentary position of rest in alinement with the discharge point between the feed-rollers 6, G, the presserfoot together with the gripping jaw are opened to form aI receiving mouth for the blank. The opening movement of the gripping finger and presser-:toot is effected through engagement of a sprlng-controlltal arm 48 which is secured to the spindle ALif) of the rocker arm, a nose of the arm 453 being arranged lto travel over the face of a fixed eam 49 that projects from the adjacent face of the stationary shell Q9. It will be observed that the presser-toot supporting arm and various connections with relation to the gripping finger are all disposed rearward of the working end of the 1nandrol so as to thus give the desired clearance for the travel of the paper blank z bout said working end.

After a blank is 'formed into a complete pompon it desirable to strip the same from the mandrel end :1nd for this purpose the mandrel is provided with a pair of oppositely disposed surface grooves 52 into which are fitted the legs 53 ol' a stripper n'leznber. 'lhe legs 53 are extended beyond the rear end of the mandrel, at which point they are connected bj an. annularly groovcd cap 541; that engages a eam-track 55 which 'forms parl of the shell 2t). The :forward ends of the stripper member legs 53 are provided with laterally extended feet 53 which project beyond the Vface of the` mandrel 'for engagen'icnt with the rear edge o'f the tubular shank of a finished pompon. 4llencc it. is apparent that owing to the contour of the cani-'flange 55, the 'feet of the stripper lingers will be caused to travel toward the outer end of the mandrel at a desired point for discharging said completed pompon in the rotation of the head. 'lne mandrels itl, as shown, are preferably lslightly tapered so as to facilitate stripping the finished pompon and also for the purpose o f forming` the tubular shank of a completed pompon C as shown in Fig. 16, slightly flared, whereby the said article can be readily inserted upon the bouc of a chop or other article.

lt should be um'lerstood that while we have shown and described a spring-controlled device for locking the lirst fold o'l': the blank to the mandrel that wc may, without departii'ig from the spirit of our invention, employ any simple 'form of vacuum deree for accomplishing the same result.

lfrom the 'foregoing description it is ap parent that with each cycle ot' the machine a series of finished pompons such as shown in lliq. .lt of the drawings are discharged tlxerefrom, the same beinglI 'formed from blanks l); such as shown in `Fig. 15. .ln the operation the paper strip traveling under the slitting rolls is perforated or serrated as shown adjacent to one edge and a line of glue .2' Ais discharged upon the surface, as indicated in -Figs. and l5. The strip thereafter travels through the 'frnfming plate 'lll and its serrated or slit edge is folded upon itself lo form a seam which is thereafter seci'lrcd by adhesion of the :faces of the folded strip incidental to the latter being passed between the feed-rollers At and 4t. '.lhe serrated and folded outer edge in its travel to the mandi-els is not creased or broken due to the 'fact that at this point the feed rollers have no contact therewith. After the 'folded st rip has passed under the first set of feedfollers it is eut into a blank fla 1,079,125

in the form shown in F ig. 15 with the exception that when this cutting operation takes place the serrated edge is folded and sealed. The cutting knife section 21 forms an oblique edge m as shown in Fig. l5, the angle of this edge being at approximately a right angle to the axis of a mandrel upon which the blank is to be wound. Incidental to a cutting operation to sever the blank section spot of adhesive material y is deposited upon the corner of the blank adjacent to its oblique edge and thereafter the blank is fed to the mandrel by engagement with the feed-rollers 5, 5', 6, 6, the feed-roller 6 being provided with a groove G so as to clear the glue-spot y. The forward edge of the blank will now pass between the mandrel and presser-foot, assuming the position shown in l? ig. 13 and co-incident to this movement the gripping finger will be released due to its cam-control. Hence said gripj'iing finger will lock or secure the forward edge of the blank to the mandrel and said mandrel will then describe a planetary movement about the axis of the head 32. Co-incident to release of the gripping finger it is apparent that the presser-foot will engage the mandrel and thus as said mandrel is rotated tension upon the strip will result. Should the mandrel in its planetary movement take up the strip faster than it is discharged by the feed-rollers G and G, provision is made to permit slippage of the feed-roller (S to thus compensate for the differential movement, the said provision being in the form of a tension spring 9', whereby the roller is held against normal rotation upon its spindle. @wing to the angular position that the mandrel assumes with relation to its initial engagement with the blank it is apparent that when said mandrel revolves that the blank will be coiled thereabout spirally and in performing the last winding of the coil the edge of the same will be wound straight with relation to said mandrel owing to the oblique cut a in the rear' edge at the corner of which the adhesive had been previously deposited. `When the last coil has been completed this adhesive deposit will cdme to rest between the presser-foot and face of the mandrel and in this position it will be held due to the fact that the pinion of said mandrel has now passed beyond the toothed rack with its shoe portion in sliding engagement with the track all. lt is also apparent that prior to the completion of the pompon just described the mandrel following has come to the position of feed and taken up a blank. The completed pompon is not discharged from its mandrel until just prior to said mandrel being placed in position for gripping a second blank, the said stripping being effected by the angular section of the cam-track 55, which section will cause the stripping mechanism to move toward theA discharge end of the mandrel and thus force the completed pompon therefrom. J ust prior to stripping of the pompon shank from the mandrel the arms 48, e8', ofthe spring-controlled lever will be actuated through engagement of arm 48 of said lever with a rise in the cam-track 49', said operation causing the presser-foot and gripping finger to release the shank of the pompon in order that thestripping mechanism may perform its function.

lt will be observed that owing to the fact that there are four mandrels upon the head that there are four distinct intermittent movements thereof and hence in order to insure alinement of mandrel with Athe feed-rollers we provide a spring-shoe he which is carried by the shell 29 and is adapted to engage flattened faces of the spindle 3l. Hence it is apparent that with each revolution of the head. a complete pompon is formed and that there is sufficient delay between the completion of the pompons and their discharge to permit setting of the final sealing connection between the last and adjacent coils. lt is also apparent that in some instances in place of winding the pom pons upon permanent mandrels we may substitute for the working end of such mandrels removable stems upon which the Shanks of the pompons may be coiled and permanently glued thereon.
